Why is it called harvest?

Excuse me, could you please elaborate on the reasoning behind the name "harvest" in the context you're referring to? Is it perhaps related to the idea of reaping rewards or gains, similar to the agricultural practice of harvesting crops? Or does it signify a period of abundance and prosperity, akin to the bountifulness of a successful harvest season? I'm genuinely curious to understand the symbolism and significance behind this term, as it seems to carry a specific and meaningful connotation.
